How to Turn Off Sleep Mode on Your Thermostat

Are you frustrated that your thermostat keeps turning off at night or when you’re away at work? Having your thermostat enter sleep mode can be a great way to save energy, but sometimes it’s nice to keep the temperature constant. Fortunately, turning off sleep mode is easy on most programmable thermostats. In this article, I’ll walk you through the step-by-step process so you can take control of your home’s temperature.

What is Sleep Mode?

Before going into how to disable it, let’s briefly go over what sleep mode is. Sleep mode is an energy-saving setting on many programmable thermostats.

The thermostat is programmed to enter sleep mode during certain time periods, usually at night when you are sleeping or away during the daytime. In sleep mode, the thermostat will let the temperature fluctuate within a wider range – generally letting it get cooler at night or warmer during the day.

For example, you may program your thermostat to be 70°F normally, but in sleep mode allow it to drop to 65°F. This helps reduce energy usage when you need the temperature control less. Sleep mode is a great feature for saving money on bills.

However, sometimes it can be annoying if you want to maintain a constant comfortable temperature. The good news is sleep mode can be easily disabled on most models.

Why Would You Want to Turn Off Sleep Mode?

Why Would You Want to Turn Off Sleep Mode?

Here are some of the main reasons you may want to disable the sleep mode on your thermostat:

  • You have a newborn or elderly family members – Maintaining a constant temperature is important for babies or older adults. The wider fluctuations of sleep mode may not be comfortable or advisable.
  • You work from home – If you work from home, having the temperature drop significantly during the day while you’re working can be unpleasant.
  • You have pets at home – Pets can be sensitive to temperature changes as well. Disabling sleep mode creates a more stable environment.
  • You sleep hot or cold – We all have different comfort preferences. If you get too hot or cold with the wider ranges of sleep mode, it’s better to keep a fixed temp.
  • You don’t want to wake up – The temperature differential of sleep mode kicking in may wake you up in the middle of the night. Keeping a fixed temperature leads to better sleep.
  • You want convenience – Maybe you just don’t want to bother programming sleep mode times and temps. Turning it off is simpler.

Whatever your reasons, turning off sleep mode is easy on most thermostats. Let’s go through the step-by-step process for different brands.

How to Disable Sleep Mode on a Honeywell Thermostat

Honeywell is one of the most popular thermostat brands. Most Honeywell programmable thermostats have a sleep mode that can be turned off. Here are the steps:

  1. Press the “Menu” button on the thermostat to enter the main menu.
  2. Use the arrow buttons to select “Settings” and press “Select” or “OK” to enter settings.
  3. Go to the “Program” submenu.

  6. Return to the main screen. Sleep mode times should now be deactivated.

Some Honeywell models may bury the sleep mode setting a little deeper in the menu. If you don’t see it in the above steps, search through the options for a “Comfort Settings” or similar menu. Just look for the setting labeled “Sleep” and turn it to Off.

Once disabled, your Honeywell thermostat will maintain the set temperature 24/7.
